<zao> VS 2019 16.7 seems to be released. Any bets on if it breaks HPX? :P

<tiagofg[m]> hkaiser: I created an example on my github, about the inheritance issue
<tiagofg[m]> the rest of the program (executable with main and heranca.cpp) are in the same repository
<tiagofg[m]> I’m hopeful that you guys know what the problem is, it’s probably a simple thing I’m doing wrong, I don't know...

<gonidelis[m]> @hkaiser yt?
<hkaiser> gonidelis[m]: here now
<gonidelis[m]> hkaiser: the cpo needs to forward to `transform_()` right?
<hkaiser> yes
<gonidelis[m]> ok... I am still working on the `hpx::transform`. The thing is that `transform_()` takes a `proj` arg. But the `hpx::transform` has nothing to do with projections (as projections are a ranges "thingy" according to augustin)...
<gonidelis[m]> So I don't know what to pass as a projection argument inside the `hpx::transform` CPO implementation
<hkaiser> pass hpx::parallel::util::projection_identity{}
<gonidelis[m]> ok makes sense since it does not interfere with the user api
<gonidelis[m]> hkaiser: Should the tag_invoke be like `return get_second_element(........)` or should it be like `return transform_(......)`. What make more sense?
<hkaiser> what does transform_() return?
<gonidelis[m]> hkaiser: `util::detail::algorithm_result<policy, util::in_out_result<>>::type`
<hkaiser> well, then you need to extract the second element from _that_
<gonidelis[m]> ok... plus. You told me that we have not touched the way the segmented algos are integrated
<gonidelis[m]> But transform_ still needs an arg for that... So I still pass an `is_segmented()` arg at the `transform_()` call inside `tag_invoke`
<hkaiser> sure
<gonidelis[m]> thank you thank you !!!!!!!! just a last one: what did you mean with your comment about the `std::transform` call
<gonidelis[m]> I should change that and instead call our own `transform` ?
<gonidelis[m]> is that right?

<diehlpk_work_> hkaiser_, Can I merge https://github.com/STEllAR-GROUP/hpx/pull/4875 without passing all tests, since it is only documentation changes?
<diehlpk_work_> I updated the branch twice but some mac os builder seems to fail
